BACKGROUND OF THE INVENTION

[0003] A disturbance (change in position or state of individualparticles) in the fabric of space-time causes a sphere of influence.Stated in a simplistic manner, the action of one particle influences theactions of the others near it. This sphere of influence is referred toas a “field”, and this field is designated as either electric ormagnetic (after the way it influences other particles). The direction oftravel of the particle is called the direction of propagation. Thepropagation of the particle, the sphere of influence, and the way itinfluences other particles is called an electromagnetic wave, and isshown in FIG. 1.

[0004] As shown in FIG. 1, the electric and magnetic fields areorthogonal (at right angles) to each other and the direction ofpropagation. These fields can be mathematically expressed as a vectorquantity (indicating the direction of influence along with strength,i.e., magnitude, of influence) at a specific point or in a given regionin space. Thus, FIG. 1A is the electromagnetic wave in FIG. 1, but withthe view of looking down the axis of propagation, that is, down the xaxis of FIG. 1. FIG. 1A shows some possible various electric fieldvectors that could exist, although it should be understood that any andall possible vectors can exist around the circle, each having differentmagnitudes.

[0005] Vectors can be resolved into constituent components along twoaxes. This is done for convenience sake and for generating a frame ofreference that we, as humans, can understand. By referring to FIG. 1B,it is shown that the electric field vector E, can be resolved into twoconstituent components, E(y) and E(x). These quantities, then, describethe orientation and the magnitude of the electric field vector along twoaxes, the x and y, although other axes or systems could be chosen. Thesame applies to magnetic fields, except that the X and Z axes would beinvolved

[0006] The ways the electric and magnetic fields vary with time inintensity and direction of propagation have been determined by severalnotable mathematicians and physicists, culminating in a group of basicequations by James Maxwell. These equations, simply applied, state thata field vector can be of one of several different states, that is: 1)the field vector varies randomly over a period of time, or 2) the fieldvector can change directions in a circular manner, or 3) the fieldvector can change directions in a elliptical manner, or 4) the fieldvector can remain constant in magnitude and direction, hence, the fieldvector lies in one plane, and is referred to as planar.

[0007] This orientation of a field vector and the way it changes withtime is called the state of polarization.

[0008] Electromagnetic waves can be resolved into separateelectromagnetic waves with predetermined orientations of a field vector.The electromagnetic waves with a predetermined orientation of a fieldvector can then be directed through materials, such as a liquid crystaldevice, that is capable of changing (or altering) their orientation ofthe field vector upon application of an outside stimulus, as isdemonstrated in FIG. 7. These devices are noted as programmableelectromagnetic wave field orientation rotating devices (PEMFVORD).

[0009] An electromagnetic wave can be characterized by its frequency orwavelength. The electromagnetic spectrum (range) extends from zero, theshort wavelength limit, to infinity, the long wavelength limit.Different wavelength areas have been given names over the years, such ascosmic rays, alpha rays, beta rays, gamma rays, X-rays, ultraviolet,visible light, infrared, microwaves, TV and FM radio, short wave, AM,maritime communications, etc. All of these are just short handexpressions of stating a certain range of frequencies forelectromagnetic waves.

[0010] Different areas of the spectrum interact with electromagneticinfluences upon them in various proportions, with the low end being moreinfluenced by magnetic fields, and the high end being influenced byelectric fields. Thus to contain a nuclear reaction, a magnetic field isused, while controlling light an electric field is used.

[0011]FIG. 2 illustrates a schematic cross section of an LCD cell. TheLCD cell 100 includes a liquid crystal material 101 that is containedbetween two transparent plates 103, 104. Spacers 105, 106 are used toseparate the transparent plates 103, 104. Sealing elements 107, 108 sealthe liquid crystal material 101 between the transparent plates 103, 104.Conductive coatings 109, 110 on the transparent plates 103, 104 conductthe appropriate electrical signals to the liquid crystal material 101.

[0012] A type of liquid crystal material 101 used in most LCD cells foroptical display systems is referred to as “twisted nematic.” In general,with a twisted nematic LCD cell, the molecules of an LCD cell arerotated in the absence of a field through a 90° angle between the upper103 and lower 104 transparent plates. When a field is applied, themolecules are untwisted and line up in the direction of the appliedfield. The change in alignment of the molecules causes a change in thebirefringence of the cell. In the homogeneous ordering, thebirefringence of the cell changes from large to small whereas theopposite occurs in the homeotropic case. The change in birefringencecauses a change in the orientation of the electric field vector for thelight being passing through the LCD. The amount of the rotation in themolecules for an individual LCD cell 100 will determine how much changein polarization (orientation of the electric field vector) of the lightoccurs for that pixel. The light beam is then passed through anothercomponent of the system (i.e., polarizer analyzer) and is resolved intodifferent beams of light by the orientation of their electric fieldvectors, with the light that has a selected predetermined component ofthe electric field vector passing through to finally strike the screenused for the display.

[0013] A twisted nematic LCD cell requires the light incident at the LCDcell 100 to be polarized. The polarized light for a typical projector isgenerally derived from a randomly polarized light source that iscollimated and then filtered by a plastic polarizer to provide a linearpolarized beam. Linear polarized beams are conventionally referred to asbeing S-polarized and P-polarized with the P-polarized beam defined aspolarized in a direction parallel to the plane of incidence and theS-polarized beam defined as polarized perpendicular to the plane ofincidence.

[0014] The development of PEMFVORD technology has resulted in thedevelopment of LCD projectors which utilize one or more LCDs to alterthe orientation of the electric field vector (see FIG. 7) of the lightbeing projected. The birefringence of the individual LCD pixels isselectively altered by suitable apparatus such as cathode ray tubes,lasers, or electronic circuit means. A typical liquid crystal lightvalve (LCLV) projector includes a source lamp which is used to generatea light beam that is directed through a polarizer. This polarized lightis directed through the LCDS to change the polarization according to theimage to be displayed. The light, after exiting the LCD, passes througha plastic polarizer analyzer which stops and absorbs the unwantedportion of light. The formed image is then enlarged with a projectionlens system for forming an enlarged picture on a display screen.

[0015] Color LCLV projectors typically include color separatingapparatus such as a prism, beam splitters or dichroic mirrors toseparate collimated white light beams from the light source into threeprimary color beams (i.e., red, green and blue beams). The red, greenand blue beams are then individually modulated by LCDs and combined byseparate optical apparatus such as combining prisms, mirrors or lenses.

[0016] In general, the quality and brightness of the projected image inany LCLV projector is a function of the brightness of the source forilluminating the LCDs and the polarizing means. Polarizing optics mustbe utilized to filter/separate the white light into light with a singleorientation of the electric field vector. The white light emitted fromthe source is thus only partially utilized (i.e., one direction ofpolarization) in most LCLV projection systems. This requires oversizedlight sources to achieve a desired brightness at the viewing screen.

[0017] Typically, with a twisted nematic transmissive type LCD cellsurrounded by plastic polarizers, only forty percent or less of theoutput of the light source is utilized. Practically, only a maximumtransmission of 50% for randomly polarized light passed through couldever be achieved because of the construction and principles involved inplastic polarizers, allowing for 100% efficiency for the device for allwavelengths. Thus, it is impossible to obtain a full brightnessprojector. Moreover, the unused polarized component of the light sourceis absorbed by the plastic polarizers and generates wasted energy in theform of heat and transfers this heat to other components (i.e., LCDs,electronics, etc.) and hence is detrimental to the system (especiallythe plastic polarizers, LCDs, electronics, etc.). This heat must beeither shielded and/or dissipated from the components of the system, orelse, the light source must be reduced in light output so that theamount of light being absorbed is below the threshold of permanentdamage to the components, including the plastic polarizers. Currently,this threshold for fabricated plastic polarizers is between the range of5-10 watts of light per square inch (0.78-1.55 watts per squarecentimeter), depending upon the wavelength of the illuminating light. Amethod for improving the damage threshold is included in U.S. Pat. No.5,071,234 to Amano, et al., although this patent does not discuss theparticulars of what the damage threshold is.

[0018] Prior art systems have required relatively complicated opticalsystems including the use of polarizing prisms and prepolarizing prismsto ensure a unitary or single polarization at the LCD and to provide asuitable resolution and contrast of the projected image with prior artcolor LCLV projectors, complicated optic components and arrangements arerequired to combine the separated color bands at a suitable resolutionand contrast.

Prior art illuminationsystems for overcoming problems with the brightness of LCD displayillumination systems have not been completely successful. Prior artillumination systems for overcoming problems with the brightness of LCDdisplay illumination systems have not been completely successful.

[0020] An example of an illumination system that attempts to utilize thefull output of a light source for increasing the brightness of an LCDdisplay is disclosed in U.S. Pat. No. 5,028,121 to Baur, et al., In theBaur system, the randomly polarized light source is resolved into twoseparate polarized beams, with one of the polarized beams passed to adichroic color splitter that then directs the segregated color beams toa set of reflecting LCDs, while the other beam of different polarizationis sent to a different set of LCDs through a different dichroicsplitter. After having each respective portion of the beams' electricfield vector altered, the beam is then reflected back through thedichroic mirrors into the polarizing beam splitter/combiner. The pictureto be represented is sent to the projection lens, while the rejectedbeam is sent back into the light source. This causes the light source toheat and have a shortened life span. Furthermore, each sequential fieldto be projected has a different brightness level illuminating eachpixel, depending upon the amount of light that is rejected back into thelight source.

[0021] For example, if a light source has an average output of 1000lumens and the sequential field to be projected has an averagebrightness level of 30% then 700 lumens would be reflected back into thelight source, making the light emitted from the source to be aneffective 1700 lumens. In the next sequential field, if the averagebrightness level is 50% then 500 lumens would be reflected back into thelight source, making the light emitted from the source to be effectively1500 lumens. This can be alleviated by computing the average brightnesslevel to be projected, and then modulating the brightness level of thelight source when the field is changed for projection so that theillumination of a pixel is at a constant brightness. This system canfurther be modified by (or be a stand alone system) that would monitorthe light output of the light source and change the driving circuitry ofthe light source to maintain a constant brightness level. This can bemonitored by a light transducer that monitors the light from a beamsplitter, or alternately, can be mounted directly on a LCD panel outsideof the picture forming active area. However, the addition of any of theabove circuitry further complicates the projector and makes the lightsource an active part of the system, increasing the cost and complexityof the projector.

[0022] Another example of an illumination system that attempts toutilize the full output of a light source for increasing the brightnessof an LCD display is disclosed in U.S. Pat. No. 4,913,529 to Goldenberg,et al. In the Goldenberg system, a beam of light, from a light source,is split into two orthogonally linear polarized beams. One of the beamsis then passed through a device that rotates one of the beams to changeits direction of polarization so that there are two beams of the samepolarization. The beams of the same polarization are then directedthrough different faces of a prism, combined by the prism and focused onthe LCD devices.

[0023] A problem with such a system is that the beams are not collinear.The beams illuminate the polarizer at different angles, causing an areaof usable light, and another area of unusable light. The result is thatall of the light available is not used. Another obstacle is that it isdifficult to align the combined beams with the use of a prism. Yetanother complication is that the prism tends to separate the light intoseparate colors. This detracts from the clarity, brightness and limitsthe resolution of the projected image. Still another complication isthat the performance of polarizers vary with the angle of lightilluminating them, causing different polarizations and different colorgradations to occur in the beam.

[0024] Other systems, such as those disclosed in U.S. Pat. No. 4,824,214to Ledebuhr, U.S. Pat. No. 4,127,322 to Jacobson, et al., U.S. Pat. No.4,836,649 to Ledebuhr, et al., and U.S. Pat. No. 3,512,868 toGorklewiez, et al. also disclose optical layouts for achieving a highbrightness in display systems that utilize LCD devices. In general,these systems are relatively complicated and contain numerous componentsthat are large, expensive, and difficult to adjust.

[0025] Representative prior art flat fluorescent light sources aredisclosed in U.S. Pat. No. 4,978,888 to Anandan, et al., and U.S. Pat.No. 4,920,298 to Hinotani, et al.

[0027] Various prior art techniques and apparatus have been heretoforeproposed to present 3-D or stereographic images on a viewing screen,such as on a polarization conserving motion picture screen.

Suitable eyewear, such as glasses havingdifferent polarizing or color separating coatings, permit the separateimages to be seen by one or the other eye. This type of system isrelatively expensive and complicated requiring two separate projectorsand is adapted mainly for stereoscopic movies for theaters. U.S. Pat.No. 4,954,890 to Park discloses a representative projector employing thetechnique of alternating polarization.

[0028] Another technique involves a timed sequence in which imagescorresponding to right-eye and left-eye perspectives are presented intimed sequence with the use of electronic light valves. U.S. Pat. No.4,970,486 to Nakagawa, et al., and U.S. Pat. No. 4,877,307 to Kalmanashdisclose representative prior art stereographic display systems of thistype.

[0029] While previous time sequential light valve systems are adaptableto display arrangements for a television set, because of problemsassociated with color, resolution and contrast of the projected image,they have not received widespread commercial acceptance. Moreover, thesystems proposed to date have also been relatively expensive andcomplicated.

[0189] Another object of this invention is to provide a method andsystem as aforesaid for modulating a beam of light.

[0190] One illustrative embodiment of the invention comprises: a lightsource for producing a collimated unpolarized beam of light; apolarizing beam splitter for splitting the unpolarized source beam intoseparate orthogonal linear P-polarized and S-polarized light beams; ahalf-wave retarded for converting the S-polarized light beam back to asecond polarized-polarized light beam; and an arrangement of mirrorsthat combines the P-polarized light beams into a rectangular shaped beamof a unitary polarization.

[0191] The light beam, at this point, is separated into a red componentand into a blue-green component using a first dichroic mirror selectedto reflect light having red wavelengths greater than 600 nanometers. Theblue-green component is then separated into a blue beam and a green beamusing a second dichroic mirror selected to reflect light having greenwavelengths between 500 nanometers and 600 nanometers. As an option, thered beam and the blue beam can be further filtered in order to providean optimum of color balance in visual effect and the rejected portionsof the beams that are filtered out from the red and blue can then beabsorbed. At this point, the separate red, green and blue beams arepassed through liquid crystal display devices and have their electricfield vectors altered according to the input signal. The separate redand green beams are combined into a red-green beam using a dichroicmirror selected to pass the green beam wavelengths less than 595nanometers and reflect the red beam. This red-green beam is thencombined with a separate blue beam utilizing another dichroic mirrorselected to pass the red-green beam wavelengths greater than 515nanometers and reflect the blue beam to form a collinear beam. Thiscollinear beam is then passed through a polarizer analyzer to segregatethe beam according its electric field vector. One of the segregatedbeams can be passed to an absorbing beam block. The selected segregatedmodulated polarized beam is passed onto a projection lens that projectsit onto a viewing screen. The system and method of the invention can beadapted for projecting a large image of high brightness, resolution andcontrast onto a screen.

[0192] It should be further understood that, while certain particularwavelength numbers have been given for red, blue and green, they are forillustrative purposes only and can be changed or shifted due to the typeof light source used. The changing or shifting of the particular rangeof wavelengths of the colors is due to the final color balance that isdesired.

[0193] In use of one system disclosed, collimated light from the lightsource is directed through the polarizing beam splitter. The polarizingbeam splitter separates the randomly polarized beam into a linearP-polarized beam and S-polarized beam and deflects the orthogonalpolarized beams at right angles to one another. The P-polarized beampasses through the polarizing beam splitter and is reflected through anangle of 90° by a first mirror and into the projector beam path. TheS-polarized beam exits from the polarizing beam splitter at an angle of90° to the P-polarization beam and passes through the half-waveretarder. The half-wave retarder changes the polarization of theS-polarized beam back to P-polarization. A second mirror then reflectsthis P-polarized beam through an angle of 90° onto a third and a fourthmirror. The third and fourth mirrors split the reflected P-polarizationbeam and again reflect the P-polarized light beam from the second mirrorthrough an angle of 90° and onto the LCD. The four mirrors are mountedalong an optic path with respect to one another such that the separateP-polarized beams are combined in a generally rectangular shaped beamthat corresponds to the rectangular light aperture of a LCD.

[0194] The system of the invention permits virtually all the light fromthe light source to be directed at the LCD. Moreover, the light beam atthe LCD has a shape that corresponds to the generally rectangular outerperipheral configuration of most LCDs. The advantages of the rectangularbeam allow the utilized light to strike the useful portions of the LCD,thereby not overheating the other elements surrounding the LCD causingreflection and/or heating problems.

[0195] Furthermore, another embodiment of the system of the inventiondirects a collimated source beam into a polarizer and divides the sourcebeam into a right side beam and a left side beam, each having the samedirection of polarization. The left side beam and the right side beamare then filtered into separate primary color beams (red, green andblue). Each separate primary color beam has the pixels of the respectiveportions of the beam changed in regards to the electric field vector byseparate LCDs responsive to left and right side input images. Therespective images of the right and left side primary color beams arethen combined into a single right and left side images. The left andright side images are then combined, resolved into different polarizedlight beams according to the electric field vector by a polarizeranalyzer and then one of said polarized beams is projected onto adisplay screen.

[0196] In yet another embodiment, a high resolution image is obtained bythe method and system as described above. The left side beam is offseton the display screen from the right side beam (or vice versa) by asmall amount in either the horizontal or the vertical direction (i.e.,one pixel). In this mode, the driving electronics of the liquid LCDsmust split an input image and provide that every other pixel is sent tothe right or to the left side.

[0197] In order to project a three-dimensional image, separate inputimages corresponding to the left and right eyes of the viewer (i.e.,different spatial perspectives) are input into the separate left andright side LCDs. A viewer has the choice of putting on a set of glassesover his eyes, such that the lens over the right eye is for viewingimages polarized in a first direction and the lens over the left eye isfor viewing images polarized in a different direction. The viewer willsee a three-dimensional image if the signal provided to the drivingelectronics for the left/right side provide for a different signalcorresponding to the different angular spatial mode of the left andright eye, i.e., the left side is a left side camera and the right sideis a right side camera. These separate left side or right side imagesmay also be viewed in three dimensions by a timed sequence for achievingthe 3-D effect without glasses.

[0198] As an example, the system is configured such that a viewer'sglasses contain a lens for viewing different orthogonally or differentcircularly polarized images. A left eye lens is configured for viewingP-polarized light while the right eye lens is configured for viewingS-polarized light. Alternately, as an example, the left eye lens isconfigured for viewing right circularly polarized light while the righteye lens is configured for viewing left circularly polarized light.

[0199] As an alternate example, the system is configured such that, inplace of the viewer's glasses, a polarized screen is used. This screenis formed of a transparent material that has two or more differentpolarization coatings or layers. Each coating or layer reflects acertain orientation of an electric field vector and passes all otherorientations of electric field vectors. Each successive layer or coatingis different from the other layers. This allows certain portions of theimage to be seen in depth or in actual 3-D. These types of layers orcoatings are available from OCLI. For a general discussion, see “OpticalThin Films User's Handbook”, by James D. Rancourt, McGraw-Hill Opticaland Electro-optical Engineering Series, 1987.

DETAILED DESCRIPTION OF THE DRAWINGS

[0255] For purposes of simplicity, the same number has been used in thevarious figures to identify the same part.

[0256] Light Path and Rectangular Beam

[0257] Referring now to FIG. 3, a collimated light beam 50 from a lightsource 32 is converted into a unitary polarized beam 30 having across-sectional configuration or shape (see FIG. 5) that matches anouter peripheral cross-sectional configuration or shape of the LCDdisplay 34. As an example, the LCD 34 display is a LCD having a lightaperture of a generally rectangular outer peripheral configuration.

[0258] This aspect of the invention includes in an optically alignedpath: a polarizing beam splitter 36, a half-wave retarder 38, and anarrangement of a first mirror 40, a second mirror 42, a third mirror 44,and a fourth mirror 46, that combine the separate beams exiting from thepolarizing beam splitter 36 into a combined beam of single polarization30 having a cross sectional configuration or shape that matches thecross sectional shape of the LCD display 34. Suitable color filters 48may be placed between the LCD display 34 and the combined beam.

[0259] The manner in which the collimated beam 50 is formed is nowdescribed. Light source 32 and reflecting optics or means 41 produce anunpolarized beam of light 50 which is then collimated by collimationoptics, such as lens 43 or light integrator means 63, as shown in FIG.27.

[0260] The light or optical integrator means is made of a plurality oflight pipes such as those shown in FIG. 27A, each light pipe beingadjacent and in contact with one or more other light pipes. Each lightpipe consists of a first lens surface 45, a body 75, and a second lenssurface 71. A light source 31 emits rays 73 towards the surface of body75 which is ground to the predetermined shape required. This first lenssurface 45 functions to bend light rays 73 towards a more collimatedalignment one to the other. Body 75 carries the light rays to the secondlens surf ace 71 and has the same index of refraction as the first lenssurface 45 and second lens surface 71. This minimizes the number ofinterfaces the light ray 73 must pass through. Continuing on, light ray73 strikes the second lens surface 71 which is ground to a predeterminedshape, and is again bent more normal; thus, the light rays exitingsurface 71 are substantially collimated. Lens surfaces 45 and 71 may ormay not be of the same shape or form and are dependent upon severalfactors, including, but not limited to, the size of the light source,the shape of the light source, the type of light source, the distancefrom the light source to the first lens surface 45, the length and sizeof body 75, the distance of the integrator second lens surface 71 to thetarget, and other factors known in the trade.

[0261] Referring again to FIG. 3, alternately, the light source 32 andits reflecting optics or means 41 form an unpolarized collimated beam oflight 50. The unpolarized collimated beam of light 50 is split by thepolarizing beam splitter 36 into separate orthogonal polarized beams, aP-polarized beam 52, and an S-polarized beam 54. The P-polarized beampasses through the polarizing beam splitter 36 and is directed onto thefirst mirror 40 and reflected through an angle of 90° as a reflectedbeam 53 and onto the LCD display 34. The S-polarized beam 54 isdeflected by the polarizing beam splitter 36 through an angle of 90° andis passed through the half-wave retarder 38. The half-wave retarder 38changes the orientation of the electric field vector of the S-polarizedbeam 54 to form a second P-polarized beam 56. This second P-polarizedbeam 56 is reflected through an angle of 90° by the second mirror 42.The third mirror 44 and fourth mirror 46 are situated to intercept thereflected second P-polarized beam 56 and split the beam into twoseparate reflected beams 58 and 60 emanating in the same direction asreflected beam 53. The three separate reflected beams 53, 58, and 60 arethen combined (see FIG. 5) into a single beam 30 having a singleorientation of the electric field vector (P-polarized) and is directedthrough suitable color filters 48 to the LCD display 34.

[0262] With reference to FIG. 4, each mirror such as first mirror 40,may be configured with a preferred geometrical shape such as a generallyrectangular or square (i.e., a square shape is a subset of a rectangularshape) outer peripheral configuration to intercept a generally circularshaped or collimated light beam (i.e. 52) such that the reflected beam(i.e., 53) from the mirror is also of a square or rectangularconfiguration. This arrangement will produce a reflected beam that isgeometrically similar to the sizes and shapes of the mirrors used, asthe geometry of the mirrors will be duplicated by the reflected beams.As shown in FIG. 5, this allows a square-shaped reflected beam 53 from afirst mirror 40, a rectangular shaped reflected beam 60 from fourthmirror 46, and a rectangular shape reflected beam 58 from third mirror44 to be aligned to produce a unitary beam at the LCD display 34 havinga generally rectangular outer peripheral configuration. This rectangularconfiguration of the unitary beam 30 matches the rectangular outerperipheral configuration of the LCD display 34 and in particular to thelight aperture of the LCD display 34.

[0263] The method and system for the invention with reference to FIGS. 3& 4 can be summarized as follows: producing an unpolarized collimatedbeam of light 50 with a light source 32; splitting the unpolarized beamof light 50 with a polarizing beam splitter 36 into separate orthogonalpolarized beams 52, 54 (i.e., a first P-polarized beam 52 and anS-polarized beam 54); directing a first orthogonal beam 52 (firstP-polarized beam 52) onto a first mirror 40 to produce a first reflectedbeam 53; directing the second orthogonal beam 54 (S-polarized beam 54)through a half-wave retarder 38 in order to convert the direction ofpolarization of the second orthogonal beam 54 (S-polarized beam) tobecome a second reflected beam 56 having the same polarization as thefirst orthogonal beam 52 (a second P-polarized beam); directing thesecond orthogonal beam 56 (second P-polarized beam) onto a second mirror42 and reflecting the beam through an angle of 90°; directing the secondreflected beam 56 onto third and fourth mirrors 44, 46 that reflect thesecond reflected beam 56 through a second 90° angle and split the secondreflected beam 56 into a third reflected beam 58 and a fourth reflectedbeam 60; and combining the separate reflected beams, i.e., firstreflected (P-polarized) beam 53, third reflected (P-polarized) beam 58and fourth reflected (P-polarized) beam 60, into a unitary beam 30 of asingle polarization and having a rectangular outer peripheral shape thatmatches the rectangular outer peripheral shape of an LCD display 34.

[0264] Mirrors 40, 42, 44, 46 or other reflecting means are to bealigned to intersect the path of the orthogonal light beams 52, 56 toproduce a unitary light beam by the combination of separate reflectedbeams 53, 58, 60 at the LCD display 34. FIG. 3 illustrates just one suchalignment pattern for the mirrors 40, 42, 44, 46 with their planarsurfaces. In the embodiment illustrated by FIG. 3, third mirror 44 andfourth mirror 46 are located on either side of first mirror 40. FIG. 3Aillustrates another possible alignment of the mirrors 40, 44 and 46 tointersect the path of the orthogonal light beams 52, 56. In theembodiment of FIG. 3A, the third mirror 44 and fourth mirror 46 are bothaligned on one side of the first mirror 40. However the resultantunitary beam at the LCD display 34 is functionally the same.Arrangements of the mirrors 40, 44, 46 other than those shown in FIGS.3, 3A, & 3C are also possible. The arrangement of mirrors in FIGS. 3A &3B are the same. Moreover, the mirrors 40, 44, 46 may be shaped andarranged to produce a square shaped beam at the LCD display 34.

[0265] Beam 30 allows substantially of the light produced by the lightsource 32 to be utilized for illuminating the LCD display 34 taking intoconsideration the form factor of the light source as shown in FIG. 4Aand described below. With beam 30, the minimal number of components(i.e., polarizing beam splitter 36, half-wave retarder 38, mirrors 40,42, 44, 46) allow these components to be easily adjusted to achieve aresultant unitary beam at the LCD display 34 that is of the desiredshape and of a single polarization (i.e., single orientation of theelectric field vector). The polarization of the resultant beam in theillustrative embodiments is in a P-polarized direction. Alternately, thebeam 30 can be configured to produce an S-polarized beam at the LCDdisplay 34, or whatever else predetermined polarization direction ischosen.

[0266] In addition, the half-wave retarder 38 may be rotated to tune thepolarization of the resultant beam 56 exiting from the half-waveretarder 38 to exactly match the polarization of the first P-polarizedbeam 52 exiting the polarizing beam splitter 36. Additionally, thepositions of the mirrors (40, 42, 44, 46) may be easily adjusted orrearranged to achieve a predetermined resultant beam of a desire outerperipheral configuration at the LCD display 34.

[0267] In FIG. 3B, half-wave retardation of the beam is realized bymeans other than the half-wave retarder 38 as used in FIG. 3A. This isaccomplished by reflecting the beam 54 (S-polarized) from the secondmirror 42, resulting in a quarter-wave retardation. Each half of thebeam is then reflected from the respective mirrors 44, 46 and furtherretarded by a quarter-wave. This results in half-wave retardation ofS-polarized beam 54 changing it into P-polarized beams 58, 60. Thesystem shown in FIG. 3B is preferred to those systems shown in FIGS. 3 &3A because less components are required. Such mirrors are available fromOCLI Corporation, Santa Rosa, Calif. as part numbers 777-QWM001, through777-QWM002.

[0268] The mirrors 42, 44, 46 as shown in FIG. 3B can be constructedwith a coating formed thereon through thin film coating techniques. Eachmirror 42, 44, 46 can act as a quarter wave retarder, besides being abroadband reflector.

[0269] Thin film coatings are also referred to as dielectric films,i.e., they are films made of materials composed of atoms whose electronsare so tightly bound to the atomic nuclei that electric currents arenegligible even under applied high electric fields. The individual filmthicknesses or layers vary over a very broad range, but they arereferred to as a thin film when the thickness of the film is on theorder of that wavelength. These films are built up in many layers, oneon top of another, and are referred to as a multilayer thin film, asschematically illustrated in FIG. 6. Each layer then reflects theappropriate wavelength or orientation of the electric field vectoraccording to its individually designed construction. These layers aretypically deposited on top of a receiving substrate by vacuumdeposition. This includes vaporizing a material and causing the vaporatoms to strike the substrate in a predetermined manner and rate. Sometypical materials are MgF₂ SiO₂ Al₂O₃ C (diamond), ZnS, TiO₂, CdS, CdTe,GaAs, Ge, Si, Ag, Au, PbS, along with many other materials.

[0270] Because dielectric materials are used, the index of refractionfor each layer is different from each adjacent layer, although in somecases they might be the same.

[0271] Light is reflected from, and transmitted through each layer (seeFIG. 6) and interface. These light wave fields that are transmitted andreflected from each interface interact with one another. Depending uponthe material chosen for the thin film and the optical thickness of thethin film, different results are achieved. A device made in this fashioncan have from one to several hundred film layers on a substrate. In oneinstance, by proper design, a coating can change the phase of incidentlinearly polarized light. In effect, this functions as a relativequarter wave plate. Several papers on this subject have been published,but in particular: “Phase Retardance of Periodic Multilayer Mirrors,”Appl. Opt., 21 (4):733 (1982), Joseph H. Appl, “Graphical Method toDesign internal Reflection Phase Retarders,” Appl. Opt., 23(8):1178(1984), “Mulitlayer Coating Design Achieving a Broadband 90° PhaseShift”, Appl. Opt., 19(16):2688, (1980), William H. Southwell.

[0272] In another design, the coating reflects the incident polarizedlight wave, and thus reinforces the P-polarized reflection. This designreflects the entire light spectrum and functions as a broadband mirror.

[0273] The components of the system producing unitary beam 30 may befabricated from commercially available parts. Light source 32 can be anysuitable lamp such as a short arc lamp, a quartz-halogen lamp, a mercuryvapor/xenon long arc lamp, etc. In general, such lamps efficientlyproduce a high intensity point source of light. They are available invarious sizes and with varying spectral qualities. Suitable commercialembodiments of high brightness light sources (greater than 15,000lumens) are manufactured by many manufacturers, including but notlimited to Optical Radiation Corporation, Azusa, Calif. Other lightsources that produce desired wavelengths and different output lumens(spectra or spectrum distribution) may also be utilized as shown in FIG.9A. Most light sources contain a spectrum of visible, infrared, andultraviolet light that are contained in different proportions respectiveto each other. Lasers can also be used as light sources.

[0274] Polarizing beam splitter 36 may be any of the known devices. Itmay be, for example, composed of a dielectric thin film stack disposedon a suitable substrate (such as glass). The stack may be fabricated byalternating layers of high and low refractive index films each with aquarterwave optical thickness, with the center of the wavelength designfor visible light at approximately 550 nanometers. At each film/filminterface, light is incident at Brewsters angle which transmitsP-polarized light and reflects S-polarized light. The number of layersare dependent upon the final outcome desired, and can be tailored forthe cost/performance tradeoff desired. It may be fashioned in the shapeof a cube of glass with the layers deposited on the diagonal, oralternatively, the multilayers can be deposited on a piece of glass, andoptionally, another piece of glass can then be cemented to the front,forming a sandwich of which the multilayers are deposed in between thetwo pieces of glass. The purpose of this is to protect the layer stackfrom abrasion or contact with the air. The arrangement of a single pieceof glass or two pieces of glass would yield a polarizing beam splitterthat is less costly to produce and weigh less than a cube polarizer.

[0275] It is desirable that the light striking the surface of the layersdo so at a 45° angle, with a small deviation from the normal of therays, thus the incidence angle between the layers and the beam of lightshould be well controlled. Such a polarizing beam splitter is describedin U.S. Pat. No. 2,403,731 to MacNeille or U.S. Pat. No. 2,449,287 toFlood and is termed a MacNeille polarizer. A commercial embodiment ofsuch a polarizing beam splitter suitable for use herein can be obtainedfrom the Perkin Elmer Corporation, Electro-Optical Division, Norwalk,Conn. or OCLI Corporation, Santa Rosa, Calif. A wavelength response fora polarizing beam splitter is shown in FIG. 10.

[0276] Typically, such coatings of thin film stacks on the diagonal ofthe polarizers and polarizing beam splitters can be coatings capable ofhandling high energy beams such as laser beams. They are capable ofhandling high wattage of incident energy per centimeter squared.

[0277] The mirror 40 (OCLI Corporation, Santa Rosa, Calif., part no.777BEM001) must be selected to be an efficient reflector of theP-polarized light at the particular wavelength required. Mirrors 42, 44,46 are selected to be either quarter wave retarders or broadbandreflective mirrors, depending upon how the system is configured. If usedas a quarter wave mirror, their part numbers are 777QWM001 and777-QWM002. if used as a broadband mirror, their part numbers are777-BBM002 and 777-BBM003. These mirror numbers are available from OCLICorporation, Santa Rosa, Calif. As an example, the mirrors can be formedof a thin film coated onto a substrate. The thin film is formed with abroadband coating for visible light. It is known that metal film mirrorsreflect P-polarized waves more efficiently than S-polarized wavesbecause of the nature of metal reflections. Because of this knownefficiency factor, the conversion of S-polarized waves to P-polarized isutilized by this invention.

[0278] Such thin film mirrors that are acceptable for use herein can beobtained from the OCLI Corporation, Santa Rosa, Calif. Thin filmcoatings are known as laser coatings and are capable of handling highenergy beams (watts divided by centimeters squared).

[0279] The half-wave retarder 38 (shown in FIG. 3A) maybe one of a classof optical elements known as retarders, which serve to change thepolarization of an incident wave. With a retarder, the light exiting hasthe orientation of the electric field vector lagged in phase behind theinput light by a predetermined amount. Upon emerging from the retarder,the relative phase is different than it was initially and thus thepolarization state (orientation of the electric field vector) isdifferent as well. A retardation plate that introduces a relative phasedifference of 90° is known as a half-wave retarder.

[0280] A half-wave retarder can be made from a biaxial crystal materialsuch as mica. Suitable retarders can also be made from sheets of plasticmaterial that have been stretched to align long chain organic molecules,thin film dielectrics (such as that made by OCLI Corporation, SantaRosa, Calif.), LCDs, reflection from mirrors coated with a thin filmdielectric, a combination of a LCD and a mirror coated with a thin filmdielectric, and quartz crystal. The half-wave retarder 38 used in theillustrative embodiment of the invention can preferably be adjusted(i.e., by rotation of the crystal) to exactly match the polarizationstate of a P-polarized light beam 56 exiting the retarder 38 (see FIG.3A) with the P-polarization state of P-polarized light beam 52 exitingthe polarizer cube 36. Other means of changing or converting thepolarization direction of a light beam other than a half-wave retardercan be employed in this application.

[0281] By way of example and not limitation, a system and methodconstructed in accordance with the invention offers the followingresults and advantages over prior art illumination systems: arectangular singularity polarized beam is created that will efficientlyfill the aperture of an LCD display; and the divergence of the resultantbeam at the LCD display is smaller than with other methods ofcombination, i.e., U.S. Pat. No. 4,913,529 to Goldenberg.

[0284] A light source 32 (i.e., a xenon short arc lamp, a quartz-halogenlamp, a mercury vapor/xenon long arm lamp, etc.) emits light which iscollimated into a source beam 50 traveling toward the left that containsa wavelength spectrum of visible, infrared and ultraviolet light. (Mostlight sources contain all of the above wavelengths of light; however,they are contained in different proportions respective to each other.See FIGS. 9 & 9A for different types of light sources). Depending on theapplication, the lamp source can be any suitable means for producing acollimated beam of light. The characteristics of the light source may betailored to a particular application.

[0285] The visible region of light that a typical person can see isbetween 400 and 700 nanometers in wavelength (this is well understoodand can be found in standard reference books or college level text books(see also photopic response curve in FIG. 10). The non-visiblewavelengths between 200 nanometers to 400 nanometers are named theultraviolet region and the non-visible wavelengths between 700nanometers and 1500 nanometers are named the infrared region.

[0286] The infrared wavelength region (greater than 700 nanometers) andthe ultraviolet wavelength region (less than 400 nanometers) eachcontribute watts of radiant light energy which are detrimental to theoptics of the system but does not contribute to normal human eyesight(see photopic response curves in FIG. 10). Because of this fact, thecollimated source beam 50 from the light source 32 is directed to theleft toward mirror 33 which is a dichroic/thin film dielectric mirror.Dichroic/thin film dielectric mirrors are able to function as wavelengthfilters. In general, these type of mirrors are constructed to transmit(i.e., pass through) all light having wavelengths longer (or shorter)than a reference wavelength and reflect the non-transmitted light. Thereflective and transmissive characteristics of mirror 33 are shown inFIG. 12.

[0287] The light wavelengths less than 700 nanometers which strike thecoating on the front surface are reflected downward (as viewed in FIG.8) by an angle of 90° toward mirror 35. The infrared portions 141 of thesource beam 50 (wavelengths greater than 700 nanometers) are transmittedthrough mirror 33 and strike a beam block absorber shown schematicallyas 161. The beam block absorber 161 can be constructed of a black pieceof aluminum (preferably with fins to radiate the heat, not shown) thatabsorbs the infrared wavelengths from the source beam 50 and re-emitsthe absorbed energy as heat, which can be carried away from the systemand not introduced into the vital components which it might otherwisestrike. Alternately, in place of a black piece of aluminum, othersuitable means for absorbing infrared wavelengths may be utilized.Additionally, suitable means of separating or filtering the infraredcomponent of the source beam 50 other than dichroic/thin film mirror 33may be utilized.

[0288] The remaining wavelengths of the source beam 50 resulting in anew source beam 55 are reflected from mirror 33 downward (as viewed inFIG. 8) by an angle of 90° and strike the front surface of mirror 35. Aswith mirror 33, mirror 35 is formed as a wavelength filter so that thevisible portion (430-700 nanometers in wavelength, see FIG. 13A) of thesource beam 55 resulting in a new source beam 57 is transmitted toward apolarizer cube 36 located in an optic path with mirror 35. Theultraviolet portion 37 of the source beam 55 (wavelengths less than 439nanometers) is reflected by an angle of 90° toward the beam blockabsorber 161 on the left. (The characteristics of the mirrors 33 and 35are outlined in FIGS. 12 & 13. Alternately, in place of dichroic/thinfilm mirror 35 and beam block absorber 161, other means for separatingand absorbing the ultraviolet components of the source beam may beprovided.

[0289] The source beam 57 is next directed toward a means 36 forpolarizing the source beam 57 into two orthogonally polarized beams. Inthe illustrative embodiment in FIG. 8 of the invention, a polarizer cube36 is utilized to separate the source beam 57 into a P-polarized beam 52and an S-polarized beam 54. It should be further understood that when apolarizer cube is mentioned, that a polarizing plate or a piece of glasswith a thin film polarizing coating deposited upon it, or a sandwich ofglass, with the thin film polarizing layers deposed in between theglasses, can also be used for construction of the system.

[0290] A suitable polarizer cube 36, in an illustrative embodiment ofthe invention, is known in the art as a birefringent polarizer. Inparticular, one useful for this application is called a MacNeillePolarizer and is described in U.S. Pat. Nos. 2,403,731 and 2,449,287,with a general discussion having previously been set forth above.

[0291] The polarizer 36, if constructed as a thin film Macneillepolarizer, is sensitive to ultraviolet and infrared portions of thelight spectrum because of the thin film coatings; thus, the wavelengthfiltering by mirrors 33 and 35 that occurs before the beam enters thepolarizer cube 36 is advantageous. This is because the ultraviolet lightcauses degradation of the internal coatings and the infrared lightcauses excessive heat buildup in the polarizer 36. The polarizercoatings start to absorb energy below 425 nanometer which will destroytheir effectiveness. (see FIG. 11 for wavelength response of a suitablepolarizer cube 36). The polarizer 36 polarizes the source beam 57 intotwo orthogonally polarized beams, beam 52 and beam 54, of equalcross-sectional areas but with different polarizations. The P-polarizedbeam 52 is propagated straight through to strike mirror 40 where it isdeflected by a 90° angle toward the left. The other polarizationcomponent of the source beam cube 36, the S portion of the source beam,i.e., beam 54, is deflected left through a 45° angle from the diagonalplane of the polarizing coating of the polarizer cube 36. ThisS-polarized beam 54 is converted or changed into a P-polarizationdirection by a suitable polarization converter such as a half-wavepolarization retarder 38, or, alternately, by reflections from coatedmirrors 42, 44, and 46.

[0292] A general discussion of half-wave retarder 38 requirements andspecifications or reflections from mirrors 42, 44, 46 have beenpreviously furnished above.

[0293] The half-wave retarder 38 thus produces a second P-polarized beam56. Second P-polarized beam 56 strikes mirror 42 and it is deflected bya 90° angle downward where it is deflected toward the left by mirrors 44and 46. Mirrors 40, 42, 44 and 46 are front surfaced broadband mirrorsthat will maintain the P-polarization of the beam. Moreover, thereflective surfaces of these mirrors 40, 42, 44 and 46 can be generallyrectangular in shape such that the beams reflected therefrom are alsogenerally rectangular in shape. This allows a resultant unitarypolarized beam to be formed with a generally rectangular outerperipheral configuration to match the light aperture of an LCD. T heresultant unitary polarized beam 30 is thus doubled in its original sizeand has the same rectangular area of the LCDs that it is going to strikeand is of one state of polarization, that is, a P-polarization.

[0294] Alternately, in place of the polarizer cube 36, any othersuitable means for producing orthogonally polarized beams (52, 54) canbe utilized. Additionally, means for converting (or changing) thepolarization of one of the beams 54 other than the half-wave retarder 38can be provided, such as reflection from coated mirrors 42, 44, 46.Moreover, other means than mirrors 40, 42, 44, 46 for combining thepolarized beams 52 and 56 can be utilized. Finally the mirrors 40, 42,44 and 46 can be placed in other arrangements for producing a resultantunitary polarized beam 30 having a shape that matches the rectangularperipheral shape of an LCD or LCD light aperture.

[0295] The rectangular polarized light beam 30 now encounters thecoating surface of mirror 80 (which functions as a filtering means)where it is split into two beams 132, 134; beam 132 is deflected upward(as viewed in FIG. 8) at an angle of 90° and beam 134 continues onthrough 80 to the left. Deflected beam 132, traveling upward, is a beamcontaining wavelengths between 600 nanometers and 700 nanometers (thered portion of the visible spectrum) or, alternately, otherpredetermined portions of the light spectrum, and of the P-polarizationstate. At this time, the beam 132 strikes mirror 82 which functions as asecond filtering means. FIG. 14 illustrates the reflectancecharacteristics of mirrors 80 and 82. As is apparent, these mirrors areselected to reflect the red portion of the visible spectrum and to allowwavelengths of less than 600 nanometers or, alternately, otherpredetermined portions of the light spectrum to pass through. Mirror 82further filters the deflected beam 132 so that it will match the CIEresponse needed for a good color balance (see FIGS. 10A & 10B). As anexample, the mirror curve (FIG. 14) of mirror 82 can be shifted towardthe right so that it will pass wavelengths below 615 nanometers or,alternately, other predetermined portions of the light spectrum andcause a deflected beam to appear deeper red to the human eye. Any“unwanted” wavelengths will pass through 82 and strike a red beam block136 while the wanted wavelengths are deflected at an angle of 90° towardthe left where they pass through a first LCD, which is termed as a redLCD 138. Beam block 136 can be fabricated in the same manner as beamblock absorber 161 previously described.

[0296] The red LCD 138 (as well as a green LCD 140 and a blue LCD 142 tofollow) is of a type that can be caused to change its birefringence,thereby altering the orientation of the electric field vector of lightpassing through it, formed in a checkerboard arrangement with individualpixels 100 (see FIG. 2A). The red LCD 138 is driven by electronics inwhich each cell alters the respective light portion by rotating thevector of the electric field according to the image that is desired tobe displayed (change by “twisting” or rotating the polarization state,see FIG. 2A, by application of a voltage). The resolution of theprojected image will depend upon the number of cells in the LCD. Adisplay of 320 horizontal pixels by 240 vertical pixels will yield adisplay of 76,800 pixels. A typical television set is 115,000 pixels.Thus, the deflected red beam 132, having now passed through the red LCD138, is now an altered red beam 144 comprising a combination ofpolarizations for the individual pixels of a display, each pixel havinga predetermined orientation of electric field vector by the drivingelectronics. As will hereinafter be more fully explained, the amount ofthe rotation in the polarization state for an individual pixel willeventually decide how much of the light for that pixel will be passedall the way through to finally strike the screen used for display. Atthis point, the altered red beam 144 strikes mirror 92 and is deflectedupward at an angle of 90°. The purpose of mirror 92 is to combine thealtered red beam 144 and altered green beam 152 (as viewed in FIG. 8).Mirror 92 thus functions as a combining means. The response curve formirror 92 is shown in FIG. 16. It is best that mirror 92 does not changethe state of polarization of the altered red beam 144 or any other beamstriking it (i.e., altered green beam 152).

[0297] The deflected (from mirror 92) altered red beam 144 thencontinues on through mirror 90 which is constructed to pass anywavelengths greater than 515 nanometers (see FIG. 17) or, alternately,other predetermined portions of the light spectrum. The purpose ofmirror 90 is to combine the combined altered red 144 and altered green152 beams with an altered blue beam 160. Mirror 90 thus also functionsas a combining means. It is best that mirror 90 does not change thestate of polarization (orientation of the electric field vector) of anybeam impingent upon it. The altered red beam 144 after passing throughmirror 90 will continue on to a final polarizer called the polarizeranalyzer 146. Polarizer analyzer 146 may also be a polarizer cubeconstructed as a MacNeille polarizer, or alternatively, as describedabove, on a single piece of glass or sandwiched between two pieces ofglass. The vector component of the individual pixel light beams that isa P orientation of the electric field vector will pass through thepolarizer analyzer 146 into a projection lens 148 and be projected as apart of beam 178 toward a screen (not shown in FIG. 8) according to themagnification of the projection lens 148. The vector component of thealtered red beam 144 that is not a P vector component (S-polarization)will be deflected by the polarizer analyzer 146 toward the left and beabsorbed by beam block 150. See FIG. 1B for a pictorial illustrationshowing how a particular vector component is resolved into twocomponents, each having a different orientation of the electric fieldvector. Beam block 150 may be fabricated in the same manner as beamblock absorber 161 previously described. Thus, the intensity of the redlight at the viewing surface is directly proportional to the amount ofrotation of the altered red beam's electric field vector.

[0298] Returning now to the single state of polarization rectangularlight beam 30, it encounters the coating of mirror 80 where it is splitinto two beams 132, 134. A red beam 132 is deflected upward and theother beam, blue-green beam 134, passes through mirror 80 and continueson to the left. The blue-green beam 134 traveling through mirror 80 andtoward the left is a beam containing wavelengths between 415 nanometersand 600 nanometers (the blue-green portion of the visible spectrum) or,alternately, other predetermined portions of the light spectrum, and ofthe P-polarization state. The response curve for mirror 80 is shown inFIG. 14. Next, the blue-green beam 134 strikes the surface coating ofmirror 84 and the green portion 154 of the beam (500-600 nanometers or,alternately, other predetermined portions of the light spectrum) isdeflected by a 90° angle upward toward the green LCD 140, while the blueportion 156 of the beam (425-500 nanometers or, alternately, otherpredetermined portions of the light spectrum) continues on throughmirror 84 and toward mirror 86 at the left. Mirror 84 functions as afiltering means, and its response curve is shown in FIG. 18.

[0299] The green beam 154 passes through the green LCD 140. Each cellalters its respective portion of the green beam by rotating theorientation of the vector of the electric field according to the imagethat is desired to be displayed. Thus, the altered green beam 152,having now passed through the green LCD 140, is an altered green beam152 comprising of a combination of polarizations for the individualpixels of a display, each pixel having a predetermined orientation ofelectric field vector by the driving electronics. The amount of therotation in the polarization state for an individual pixel willeventually decide how much of the light for that pixel will be passedall the way through the polarizer analyzer 146 to finally strike thescreen (not shown in FIG. 8) used for display. At this point, thealtered green beam 152 strikes mirror 92. As previously stated, thepurpose of mirror 92 is to combine the altered green beam 152 with thealtered red beam 144 (see FIG. 17). The altered green beam 152 passesthrough mirror 92 and propagates upwardly. Mirror 92 does not change thestate of polarization of the altered green beam 152 or any other beam(altered red beam 144) striking it.

[0300] The altered green beam 152 then continues on through mirror 90because mirror 90 will pass any wavelength greater than 501 nanometers(see FIG. 17) or, alternately, other predetermined portions of the lightspectrum. As previously stated, the purpose of mirror 90 is to combinethe altered blue beam 160 (see FIG. 16 for response curve of mirror 92)with the combined, altered beams 144 and 152. It is also preferable thatmirror 90 does not change the state of polarization of any beamimpingent upon or passing through it.

[0301] After passing through mirror 90, the altered green beam 152 nowcontinues on through the polarizer analyzer 146. Any portion of thelight of the individual pixels of altered green beam 152 that is of aP-polarized orientation will pass through the polarizer analyzer 146into the projection lens 148 and be projected as part of beam 178 towardthe screen (not shown) according to the magnification of the projectionlens. The vector component of the altered green beam 152 that is not a Pvector component (S component) will be deflected by the polarizeranalyzer 146 toward the left and be absorbed by the beam block 150.Thus, the intensity of the green light at the viewing surface isdirectly proportional to the amount of rotation of the green beam'selectric field vector.

[0302] Returning now to the blue-green light beam striking the coatingsurface of mirror 84 where it is split into two beams 154, 156, a greenbeam 154 is deflected upwardly at an angle of 90° and a blue beam 156continues through mirror 84 to the left. The blue beam 156 travelingthrough 84 toward the left is a beam containing wavelengths between 415nanometers and 500 nanometers (the blue portion of the visible spectrum)or, alternately, other predetermined portions of the light spectrum, ofthe P-polarization state. The blue beam 156 continues on toward the leftand strikes the surface coating of mirror 86 (mirror 86 may be a frontsurface broadband mirror; however, it must retain the P state ofpolarization for the blue beam) and the blue beam (415-500 nanometersor, alternately, other predetermined portions of the light spectrum) isdeflected at an angle of 90° upward toward the mirror 88. A waveresponse for mirror 84 is shown in FIG. 15.

[0303] At this time, the reflected blue beam 156 from mirror 86 strikesmirror 88 for further filtering. Further filtering can be done by mirror88 on the blue beam 156 so that it will match the CIE response neededfor a good color balance (see FIGS. 10A, 10B). For instance, mirror 88can be constructed with a mirror curve as shown in FIG. 18 which isshifted toward the left so that it will transmit wavelengths above 495nanometers or, alternately, other predetermined portions of the lightspectrum, and cause the beam to appear deeper blue to the human eye. Any“unwanted” wavelengths will pass through mirror 88 and strike a bluebeam block 158 while the wanted wavelengths are deflected at an angle of90° toward the right where they pass through the blue LCD 142. Blue beamblock 158 may be constructed in the same manner as beam block absorber161 previously described. As before, it is important that mirror 88 doesnot change the state of polarization of the blue beam 156. The blueportion of the blue beam 156 passes through the blue LCD 142. Each cellalters the respective light portion by rotating the vector of theelectric field according to the image that is desired to be displayed.Thus, an altered blue beam 160, having now passed through the blue LCD142, is now an altered blue beam comprising a combination ofpolarizations for the individual pixels of a display, each pixel havinga predetermined orientation of electric field vector by the drivingelectronics. The amount of the rotation in the polarization state for anindividual pixel will eventually decide how much of the light for thatpixel passes all the way through to finally strike the screen (not shownin FIG. 8) used for display. At this point, the altered blue beam 160strikes mirror 90 and is reflected upward at an angle of 90° (as viewedin FIG. 8) for combining with altered red beam 144 and altered greenbeam 152. Mirror 90 will allow any wavelengths less than 500 nanometers,to be reflected (see FIG. 17) or, alternately, other predeterminedportions of the light spectrum. It is important that mirror 90 does notchange the state of polarization of the altered blue beam 160, or anyother beam striking it. The altered blue beam 160 now continues on tothe polarizer analyzer 146. The vector component of the individual pixellight beams that is of a P-polarized component will pass through thepolarizer analyzer 146 into the projection lens 148 and be projected asa part of beam 178 toward the screen according to the magnification ofthe projection lens. The vector component of the altered blue beam 160that is not a P vector component (S vector component) will be deflectedby the polarizer analyzer 146 toward the left and be absorbed by thebeam block 150. Beam block 150 can be fabricated in the same manner asbeam block absorber 161 previously described. Thus, the intensity of theblue light at the viewing surface is directly proportional to the amountof rotation of the blue beam's electric field vector.

[0304] At this point, all of the colors of the display (red, green andblue) have passed through the system and the projection lens 148 to beprojected 178 onto the screen (not shown in FIG. 8). They are combinedon top of each other to produce a pixelized image that has the correctcolor balance.

[0305] The projection lens 148 is either a single lens or a combinationof lenses that produces a good focused image on the screen. It has aback focal point of the distance equal to the distance from the rear ofthe lens to each one of the LCDs 138, 140, 142 in the system. Thisdistance is made the same for all of the three LCDs.

[0306] Thus, to focus and align the system, it is necessary to firstproject one of the individual colors without the others. When this isdone and the image is focused, then the second color is projected alongwith the first color and the second color LCD is moved spatially toproduce a sharp image or pixel on top of the first color pixel. Theentire image of the second color is then aligned to the image of thefirst color to make a perfect match with regard to size, focus andalignment.

[0307] Next, the second color is then turned off or blocked and then thethird color is projected along with the first color and the third colorLCD is moved spatially to produce a sharp image or pixel on top of thefirst color pixel. The entire image of the third color is then alignedto the image of the first color to make a perfect match with regard tosize, focus and alignment.

[0308] The image is then projected as beam 178 with all colors turned onand a final adjustment can then be made at this time.

[0309] The selection of the wavelengths applicable to mirrors 82 and 88can be judicially applied so that the color balances of different lampscan be adjusted for color balance of the final output without theredesign of the entire optical system (see FIGS. 10A & 10B).

[0310] When the image was projected, it was noted unexpectedly that thebrightness of the image was increased as the distance from the projectorlens to the screen increased up to a distance of approximately 10 feet(about 305 cm.). Within this range of approximately 10 feet (about 305cm.), the picture became brighter as it enlarged rather than dimmer ashad occurred in the past. When this phenomena was discovered, it wasnoted that the length of the optical path between the projector lens 148and each of the LCDs 138, 140 and 142 was approximately 13.5 in (about34 cm). The component parts shown in FIG. 8 were arranged in plan viewas shown in FIG. 8 and were encompassed with a rectangle approximately24 inches by 36 inches (about 61 cm. by 92 cm.)

[0311] While this phenomenon is not fully understood, it is believedthat this unique effect was due to the polarized nature of the light anddestructive interference of the projected light waves. It is thought atthis time that, when the picture is smaller, more wave nodes interferein a smaller area, thus the light reaching the screen is reduced. As thepicture is enlarged, the wave nodes are spaced further apart and lessinterference occurs. At a certain size, no interference takes place,and, thus, as the distance increases, the picture brightness (asmeasured in lumens/sq. ft. or lumens/sq. meter) then diminishes withgreater enlargement.

[0312] It is thought at this time that the reason this phenomena occursin this projector and not in previous projectors is the unitarypolarization of the projected beam 178. This projector uses the samepolarization for the entire beam path with the same polarizers, with theprevious projectors using individual polarizers for each of the LCDs, ofwhich different alignment of the electric field vectors occur.

[0313] An analysis of the efficiency of the system constructed inaccordance with the invention versus a prior art system that utilizes anabsorbing type of polarizer for illuminating an LCD display is asfollows:

[0314] With reference to FIG. 8.

EXAMPLE ONE Prior Art Absorbing Type of Polarizer (Kodak or SharpProjector)

[0315] lumens of light emitted by the light source=L area of circle oflight=A_(cir)=π·r² area of aperture ofLCD=A_(LCD)=length·width=6d·8d=0.48d²=0.48 (2r)²=0.48·(4r²)=1.92r² (fora 3:4:5 LCD)

[0316] % of light impingent upon LCD due to aperture ofLCD=A_(LCD))/A_(CIR)=1.92r²/πr²=61.1%

[0317] % of light passed by absorption polarizer=total light %−absorbed%=100%−70%=30%

[0318] amount of light impingent upon LCD=light output of lamp·% oflight impingent upon LCD due to aperture of LCD·% of light passed bypolarizer=L·0.611·0.30

[0319] For a lamp that emits 1000 lumens and for a one inch diagonalLCD, the light coming through an LCD is =1000·0.61·.0.30=183 lumens.

[0320] This analysis, of course, does not deal with the otherinefficiencies of the system, such as the second plastic polarizerefficiencies, the collection efficiency of the lamp, or thetransmittance efficiency of the LCDs in the system.

EXAMPLE TWO System of the Invention (FIG. 8)

[0321] lumens of light emitted by the light source=L

[0322] area of circle of light=A_(CIR)=π·r²

[0323] area of aperture ofLCD=A_(LCD)=length·width=6d·8d=0.48d²=0.48·(2r)²=0.48·(4r²)=1.92r² (fora 3:4:5 LCD)

[0324] % of light impingent upon LCD due to aperture ofLCD=A_(LCD)/A_(CIR)=1.92r²/πr²=61.1% of light passed to LCD=% of lightimpingent upon LCD to aperture ofLCD=A_(LCD)/A_(CIR)=1.92r²/πr²=61.1%·efficiency ofpolarization=(0.611·0.97)·100=59%. Therefore, for a lamp that emits 1000lumens and a one inch diagonal LCD, the light coming through an LCD is1000·0.59 or 590 lumens.

[0325] This gives an improvement over the prior art system by a factorgreater than 3.2.

[0326] Referring to FIG. 8A, a functional description of FIG. 8 is shownwith the same parts, but with the part numbers removed for clarity. Theparts are grouped according to functionality, however other parts can besubstituted, removed, or added according to what is needed to beachieved. FIG. 8A shows the steps involved to achieve a method of thisinvention.

[0327] In FIGS. 8 & 8A the light source 32, the reflector 41, thecollimating lens 43, mirror 33, mirror 35 and beam stop 161 work inaccordance together, as detailed in the description of FIG. 8 above, forproducing a beam of light 57 for the projector described.

[0328] The initial resolving of the light beam 57 is accomplished whenit is sent through the polarizing means 36, as detailed in thedescription of FIG. 8 above, and initially resolved into twoorthogonally polarized light beams 52, 54. The initial resolving mayalso include a retarding of the beam by passing it through a half-waveretarder to produce a light beam 56 which is of the same polarization asthat of light beam 52.

[0329] The forming of the light beam 30 occurs when the two light beamsare respectively reflected from forming means 40, 42, 44, and 46, asdetailed in the description for FIGS. 3, 3A, 3B & 3C above, into asingle beam of light 30 as depicted in FIG. 5. Arrangements of theforming means 40, 44, 46 other than those shown in FIGS. 3, 3A & 3C arealso possible. The arrangement of forming means in FIGS. 3A & 3B are thesame. Moreover, the forming means 40, 44, 46 may be shaped and arrangedto produce a rectangular or square shaped beam, or any other desiredgeometrical shape.

[0330] The separating of the beam, as described above for FIG. 8, isachieved by passing this beam through the separating means 80, 84, 86.The formed polarized light beam 30 encounters the separating means 80where it is separated into two beams 132, 134. Deflected beam 132travels upwardly. The beam 134 strikes separating means 84 where it isseparated into two beams 154, 156. Deflected beam 154 travels upwardly.The beam 156 strikes separating means 86 where deflected beam 154travels toward the top.

[0331] Altering of the separate beams is achieved by passing the beamthrough the LCDs 138, 140, 142 or other suitable altering means, asdescribed above for FIG. 8. Each beam passes through its respective LCD.Each cell alters its respective portion of a beam by rotating theorientation of the vector of the electric field according to the imagethat is desired to be displayed. Thus, an altered beam, having nowpassed through the LCD, is an altered beam comprising a combination ofpolarizations for the individual pixels of a display, each pixel havinga predetermined orientation of electric field vector by the drivingelectronics. The amount of the rotation in the polarization state for anindividual pixel will eventually decide how much of the light for thatpixel will be passed all the way through the polarizing means 146 tofinally strike the screen (not shown in FIG. 8A) used for display.

[0332] The adjusting of the beams 132, 156 is accomplished by passingthe beam through the adjusting means or mirrors 82, 88 and the beamstops 136, 158. Any “unwanted” wavelengths will pass through mirrors oradjusting means 82, 88 and strike beam block 136, 158 while the wantedwavelengths are deflected at an angle of 90° toward the respective LCD.Beam blocks 136, 158 can be fabricated in the same manner as beam blockabsorber 161 previously described above, as detailed in the descriptionof FIG. 8 above.

[0333] The combining of the beams 144, 152, & 160 is accomplished bypassing the beams through the combining means or mirrors 90, 92.However, these combining means can also be used for adjusting if sodesired by their beam pass/reflection criteria. The altered beam 134travels through combining means or mirror 92, while altered beam 144 isdeflected from combining means 92, which serves to combine the two beams144, 152 into a single beam. It is preferable that combining means 92does not change the state of polarization of any beam impingent upon orpassing through it. This combined beam travels through reflecting means90. It is preferable that combining means 90 does not change the stateof polarization of any beam impingent upon or passing through it. Thepurpose of combining means or mirror 90 is to combine the combinedaltered 144 and altered 152 beams with an altered beam 160 into a singlecombined altered beam, as detailed in the description of FIG. 8 above.

[0334] After the beams have been combined into a single beam they aredirected toward the resolving means where they are separated into twobeams by passing the beam through the polarizing beam splitter means146, with the desired separated beam being passed to the projectingmeans 148, as detailed in the description of FIG. 8 above.

[0335] The projecting means 148 can be either a single lens or acombination of lenses that produces a good focused image on the screen.It has a back focal point of the distance equal to the distance from therear of the lens to each one of the altering means 138, 140, 142 in thesystem. This distance is made the same for all of the three alteringmeans.

[0336] While the description above has been particularly shown anddescribed with reference to preferred embodiments thereof, it will beunderstood by those skilled in the art that various changes in form anddetails can be made without departing from the spirit and scope of thisinvention.

[0337] Referring to FIG. 8B, another alternative embodiment of the colorLCLV projector as taught in FIG. 8 is shown. FIG. 8B is an improvementover U.S. Pat. No. 4,909,601 to Yajima et al., assigned to Seiko EpsonCorp., utilizing the new and novel method and system of a singlepolarized light beam as disclosed herein. The alternate embodiment inFIG. 8B utilizes a different layout of the optical path of theinvention. As previously stated in connection with FIG. 8, a polarizedwhite light beam 30 is formed for use in the optical system. At thispoint, the white light beam 30 strikes mirror 80 and is divided into twobeams, a red beam 132, and a blue-green beam 134. Continuing on withbeam 132, it strikes mirror 82 and is deflected toward the left (asviewed in FIG. 8B) and passes through LCD 138. At this time, theorientation of the vector of the electric field is rotated responsive toa control signal input means (see FIG. 19) forming beam 144. Beam 144 isthen deflected from the dichroic beam combiner 93 and, in particular,the dichroic surface 94 and is reflected upward (as viewed in FIG. 8B)through the polarizer analyzer 146. At this point, the red beam 144 issegregated according to the P and S vector components, with the P vectorpassing on through the analyzer 146 and the S vector componentdeflecting to the left to strike beam stop 150. Returning to beam 134,the blue-green beam 134 strikes dichroic mirror 84 and is separated intoa green beam 154 and a blue beam 156. Green beam 154 is deflected upward(as viewed in FIG. 8B) through the green LCD 140 where it is alteredwith respect to the orientation of the electric field vector responsiveto a signal input means (see FIG. 14). The altered green beam 152 entersthe dichroic beam combiner 93 and passes through surfaces 94 and 96. Thebeam continues on through into polarizer analyzer 146. The P vectorcomponent passes on through to projection lens 148 with the S vectorcomponent of the beam being diverted to the left and striking beam stop150. Returning now to blue beam 156, it is deflected from mirror 86upward (as viewed in FIG. 8B) where it strikes dichroic mirror 88 and isdeflected to the right and passes through LCD 142. At this point, it hasthe orientation of the electric field vector altered by response to acontrol signal input means (see FIG. 19) and forms blue beam 160. BlueBeam 160 then enters the dichroic beam combiner 93 and is deflectedupwardly (as viewed in FIG. 8B) via surface 96 to enter the polarizeranalyzer 146. At this point, the blue beam 160 is segregated accordingto the P and S vector components that have been formed with the P vectorcomponent of beam 160 passing through the analyzer 146 to projectionlens 148 and the S vector component of beam 160 being deflected to theleft (as viewed in FIG. 8B) to strike beam stop 150.

[0338] Referring now to FIG. 8C, an alternative embodiment of FIG. 8 ofthe color LCLV projector is shown. FIG. 8C is an improvement over U.S.Pat. No. 4,864,390 to McKechnie et al., assigned to North AmericanPhilips Corp., utilizing the new and novel method and system of a singlepolarized light beam as disclosed herein. The alternative embodimentshown in FIG. 8C is functionally the same as that in FIG. 8 with theaddition that the optical path lengths from the LCDs to the light sourceare exactly the same and the optical paths of the LCDs to the beamcombiner and output lens are the same. Operation and function of thissystem is the same as that of FIG. 8. It should be further understoodthat this FIG. 8C can have the optical layout of the LCD path duplicatedand used as the second modulation subsystem to create a beam to inputinto polarizer combiner 146 to form a 3-D projector the same as thatdisclosed in FIGS. 20, 20A & 20B.

[0339] Referring now to FIG. 8D, an alternative embodiment of the colorLCLV projector as taught by FIG. 8 is shown. FIG. 8D is an improvementover U.S. Pat. No. 4,850,685 to Kamakura et al., assigned to Seiko EpsonCorp., and U.S. Pat. No. 4,943,154 to Kiyatake et al., assigned toMatsushita Electric Industrial Co. utilizing the new and novel methodand system of a single polarized light beam as disclosed herein. Thealternative embodiment of FIG. 8D operates and functions exactly thesame as that of FIG. 8 with the exception that the separate dichroicbeam splitters and combiners 80, 82 & 84 have been replaced withcombined beam splitters and combiners 93. In light of the hereindisclosed embodiments, it will now be understood that the splitting andcombining system with respect to the others can be duplicated to createanother beam that would be input into polarizer analyzer 146 to create a3-D projector that functions and operates as those shown in FIGS. 20through 20B inclusive.

[0340] In reference to FIG. 8D, as further explanation, the white lightsource beam 30 strikes the first dichroic color separator 93 and isseparated into red beam 132, green beam 154 and blue beam 156. Greenbeam 154 is passed through green LCD 140 and has its individual portionsaltered with respect to the orientation of the electric field vectorresponsive to a control means input forming altered green beam 152. Thisaltered green beam 152 then passes through the beam combiner 93 withouthaving its orientation of electric field vector changed and issegregated at polarizer analyzer 146 according to the P component and Scomponent with the P vector component passing through to the projectionlens 148, and S component being rejected upward to beam block 150 whereit is absorbed. Returning now to red beam 132, it is deflected frommirror 83 to the left (as viewed in FIG. 8D) to mirror 82 and then frommirror 82 where it is deflected downward (as viewed in FIG. 8D) throughLCD 138. Passing through LCD 138, the beam 132 has its individualportions altered with respect to the orientation of the electric fieldvector and forms altered red beam 144. Altered red beam 144 is thendeflected from surface 94 to the left (as viewed in FIG. 8D) topolarizer analyzer 146. At this point, altered red beam 144 issegregated according to the P and S components with the P componentpassing on to projection lens 148 and the S component being deflectedupward (as viewed in FIG. 8D) to beam block 150. Returning now to beam132 being deflected from surface 82, it can be further filtered at thispoint with the desired wavelengths passing to the left (as viewed inFIG. 8D) to be absorbed by beam block 136. Returning now to blue beam156 coming out of the first dichroic beam splitter 93, it is deflecteddownward (as viewed in FIG. 8D) from surface 96 and is deflected to theleft (as viewed in FIG. 8D) from surface 86. Blue beam 156 is thendeflected from mirror 88 upward (as viewed in FIG. 8D) through the blueLCD 142. LCD 142 then functions to alter the individual portions of bluebeam 142 by changing the orientation of the electric field vectorresponsive to a control signal input means (see FIG. 19) and formsaltered blue beam 160. Blue beam 160 is then reflected to the left (asviewed in FIG. 8D) from surface 96 and is passed through polarizeranalyzer 146. At this point, blue beam 160 is resolved into the P and Scomponents with the P component passing through to the lens 148 and theS component being deflected upward (as viewed in FIG. 8D) to be absorbedby beam block 150.

[0341] Returning now to blue beam 156, when it strikes mirror 88, thedesired filtering can take place with the unwanted wavelengths of bluebeam 156 passing to the left (as viewed in FIG. 8D) to be absorbed bybeam block 158 with the desired wavelengths being deflected upwardly.

[0342] Yet another alternative embodiment of a color LCLV projector isshown in FIGS. 8E through 8G. The alternative embodiment in FIG. 8Eutilizes independent light sources 170, 172 & 174 for forming a beamthat is used to alter the orientation of the electric field vector byLCDs 138, 140 & 142. These light sources 170, 172 & 174 in FIGS. 8E, 8Fmay be of several different forms and functions. Such light sources caninclude a matrix of linear array diodes formed in a rectangular shape, aplanar matrix of solid state lasers, LEDs light emitting diodes, etc.,whereas in FIG. 8G, the light sources 170 a, 172 a & 174 a can be asingle beam output laser beam with an output beam converted into arectangular shape for use by LCDs 138, 140 and 142. The light sourcesform respectively, beams 194, 196 and 198. In FIG. 8E, after each beamhas the respective portions of their beams altered by the LCDs 138, 140and 142 changing the orientation of the electric field vector of therespective portions, the altered beams 144, 152 and 160 are thencombined in dichroic beam combiner means 93 to form a single collinearbeam with a plurality of portions. This collinear beam is then passed tothe polarizer analyzer 146 where it resolves the respective portionsinto P and S components with the S component being deflected to the leftto beam block 150 and the P component passing through to the projectionlens 148 where it is then displayed on a screen (not shown in FIG. 8E).

[0343] Yet another alternative embodiment of the color LCLV projector isshown in FIG. 8F. However, the dichroic beam combiner 93 has beenreplaced by two separate dielectric mirrors 90, 92 that function tocombine the three individual beams into a single collinear beam.

[0344] In another embodiment shown in FIG. 8G, the light sources 170 a,172 a, 174 a are single beam output lasers such as are found in a gastype of laser. The output is converted to a rectangular output. The restof FIG. 8G functions and operates exactly as in FIG. 8E.

[0345] By way of example and not limitation, a system and methodconstructed in accordance with the invention offers the followingresults and advantages over prior art illumination systems for a LCLVprojector.

[0346] A rectangular singular polarized beam is created that willefficiently fill the aperture of an LCD display thus maximizing theoutput of light from an LCD projector.

[0347] The divergence of the resultant beam at the LCD display issmaller than with other methods of combination, i.e., U.S. Pat. No.4,913,529.

[0348] The system of the invention enables projectors to utilizebrighter light sources for projection, thus enabling the person viewingthe projection to see the projection source in higher ambient lightlevels.

[0349] With the system of the invention, projectors will be brighter andlighter.

[0350] With the system of the invention, projectors will consume lessenergy due to the more efficient light source.

[0351] With the system of the invention, television projected on thelarger screen video will be easier to watch.

[0352] Method for Producing a High Resolution or 3-D Projected ColorImage

[0353] With reference to FIG. 19, a schematic flow diagram of a methodfor producing a high resolution or 3-D projected color image is shown.The method and system for the invention can be summarized as follows:producing a collimated source beam of white light; separating andabsorbing infrared and ultraviolet components from the source beam;polarizing and separating the source beam into two separate orthogonallypolarized beams; changing a polarization direction of one of theorthogonally polarized beams to produce two polarized beams of the sameorientation of the electric field vector and directing each of theseparate polarized beams, respectively, to a left or a right side of theprojector; separating the polarized left side beam and the polarizedright side beam into separate polarized primary color beams (red, green,blue); further filtering the separate polarized primary color beams toprovide a color balance; alter the orientation of the electric fieldvector of the separate polarized primary color beams with separate LCD'seach of which is responsive to separate signal input means; (for 3-Dviewing, the signal input means for the left side corresponds to a lefteye image and the signal input means for the right side corresponds to aright eye image; in either case (3-D or high-resolution), the separateright side and left side signal input means are controlled by suitableelectronic control means 66. It is to be understood that controlelectronics 66 can separate the video signal of HDTV into right and leftvideo signals. As a result, this allows 3-D TV by use of the broadcaststandard for HDTV.]; combining the altered separate polarized primarycolor beams; combining altered left and right side color beams into aunitary altered beam; resolving the combined beams according to the P &S vector components of the altered beams; projecting the unitary alteredbeam onto a viewing screen; (for 3-D viewing, a viewer may wear eyeglasses having lens for viewing a left eye or a right eye imagepolarized in different directions).

[0354] Referring now to FIG. 20, a projector constructed in accordancewith an illustrative embodiment of the invention is shown. FIG. 20 islabeled with locative directions illustrating an optic path forconvenience sake only and does not necessarily resemble what the actuallayout may be. As long as all of the components are aligned in suitableoptic paths with one another, other arrangements of the illustrativecomponents arranged other than illustrated in FIG. 20 can be utilized.

[0355] Referring to the previous section, a source beam 57 is generatedfor input to the polarizer cube 36. The polarizer cube 36 separates andpolarizes the source beam 57 into two orthogonally polarized beams, beam52 and beam 54, of equal area and with different polarizations. AP-polarized beam 52L is propagated straight through the polarizer cube36 to enter the left side of the projector. The other polarizationcomponent of the source beam 57, the S-polarized portion of the sourcebeam 57, beam 54, is passed through a half-wave retarder 38 where it isconverted or changed into a beam 52R of P-polarization. Beam 52R is thenpassed into the right side of the projector. Both the left side andright side of the projector thus function with beams 52L and 52R of thesame polarization. Alternately, the projector is constructed to operatewith beams of a different polarization direction, i.e., S-polarized.

[0356] Half-wave retarder 38 may be one of a class of optical elementsknown as retarders, which serve to change the polarization of anincident wave. With a retarder, one component of the P-polarized lightis somehow caused to lag in phase behind the other component by apredetermined amount. Upon emerging from the retarder 38, the relativephase of the two components is different than it was initially and thusthe polarization state is different as well. A retardation plate thatintroduces a relative phase difference of 900 is known as half-waveretarder. Alternately, mirrors may be used to produce a light beam thathas been retarded appropriately.

[0357] A general discussion of half-wave retarder 38 requirements andspecifications has been previously discussed above. Additionally, inplace of the polarizer cube 36, any other suitable means for separatingthe source beam 57 and for producing orthogonally polarized beams (52,54) may be utilized.

[0358] The left and right sides of the projector, which are enclosed ina broken line in FIG. 20 and labeled as such, will now be described. Theleft side and the right side of the projector include identicalcomponents arranged in identical optical paths. However, the parts havean additional L or R added to distinguish one from the other. Simplystated, both the left and right side include: means (mirrors 80 and 84)for separating a polarized beam of white light (52R or 52L) intoseparate primary color beams, red, green, blue; means in the form ofLCDs 138, 140, 142, for altering the orientation of the electric fieldvector of individual portions of the separate polarized primary colorbeams responsive to separate signal input means controlled by a separateelectronic control means 60 (FIG. 19); and means (mirrors 92, 90) forcombining the altered separate polarized primary color beams.

[0359] Two separate beams, beams 62L and 62R, formed by the left sideand right side of the projector, respectively, are combined andsegregated a final time by a polarization analyzer 146 (combining andsegregating means) and projected by a projector lens 148 as a beam 178onto a viewing screen (not shown in FIG. 20).

[0360] Suitable electronic control means 66 (FIG. 19) control andcoordinate the input signals to the separate left side and right sideLCDs (138, 140, 142). For 3-D viewing, the electronic control means maybe constructed to provide a visual image to the left side correspondingto a left eye image, and to the right side corresponding to a right eyeimage. Additionally, the left eye image and the right eye image can besuperimposed with one another or timed sequentially. For example, asshown in FIG. 20, locatively, the right side can be moved up or down bymechanical or electrical means (not shown). For a high resolutionprojected image, the control means 66 can be constructed to provide avisual image to the left side which is offset from the visual imageprovided to the right side (i.e., offset by one pixel vertically orhorizontally).

[0361] For convenience sake, the identical components of the left sideand the right side of the projector are labeled with the same referencenumerals. Left side polarized light beam 52L enters the left side of theprojector and right side polarized light beam 52R enters the right sideof the projector. The operation of the left side is as previouslydescribed in the section on the color projector above and shown in FIG.20. The operation of the right side is the same with the distinction ofdifferent locative directions of the various light beams.

[0362] At this point, the beam 62L formed by the left side istransmitted into the bottom (locative direction only) of the polarizeranalyzer 146 and the beam is segregated according to the P and Scomponents of the electric field vector. The beam 62R formed by theright side of the projector is passed into the right side of thepolarizer analyzer 146 (locative direction only) and is accordinglysegregated to the P and S components of the electric field vector. Thecolor beams to be displayed (red, green and blue) have passed throughthe system and the projection lens 148 to be projected onto the screen(not shown in FIG. 20); they are combined or superimposed on each otherto produce a pixelized image that has the correct color balance. Theright side of the projector functions in exactly the same manner withthe same components. Before entering the polarizer analyzer 146,however, the polarization of right side beam 62R must be changed by thehalf-wave retarder 39 so that the right side beam 62R will be deflectedby a 90° angle for combination with the left side beam 62L.

[0363] The projection lens 148 considerations and its proximity to ascreen have been previously discussed above.

[0364]FIG. 21 illustrates such a 3-D application of a projectorconstructed in accordance with the invention. As shown in FIG. 21, ascene 70 is photographed with a left side camera 72 and a right sidecamera 74. The left side camera 72 provides an input signal 76 to theleft side of the projector 81, while the right side camera 74 providesan input signal 78 to the right side of the projector 81. The electroniccontrol means 66 (FIG. 19) may be operated as previously described toprovide these separate inputs into the projector 81 from the left sideinput 76 and the right side input 78. The left side image may bepolarized in a first direction and the right side image polarized in adifferent direction. By using viewing glasses 220, an image projectedonto a viewing surface or screen 87 appears displayed as 3-D to viewers224. Alternately, the control means 66 is configured to display leftside and right side images in a timed sequence. This will also produce a3-D effect with or without the use of glasses 220.

[0365] The alternate embodiment shown in FIG. 20A is the same as thepreferred embodiment of FIG. 20 with the addition of a quarter-waveretarder 188 situated in an optic path between the projection lens 148and the polarizer analyzer 146. The alternate embodiment projector ofFIG. 20A can be used to provide a projected image which is circularlypolarized. This can be used, for example, for providing circularlypolarized left and right side images for use with circularly polarizedviewer glass lens for 3-D projection.

[0366] Yet another alternate embodiment is shown in FIG. 20B. Thealternate embodiment of FIG. 20B is almost the same as the alternateembodiment of FIG. 20A which added the quarter-wave retarder 188. Theembodiment of FIG. 20B, however, also includes a second polarizeranalyzer 190 (on which is mounted the half-wave retarder 39 andquarter-wave retarder 188) and rejection beam block 192 situated in anoptic path between right side mirror 90R and polarizer analyzer 146. Thesecond polarizer analyzer 190 is used to further analyze, segregate andcombine the altered color beams 62R and 62L.

[0367] In FIG. 20C (another alternative embodiment of the color LCLV 3-Dprojector), there are now two constituent parts. Each constituent partgenerates a collinear beam as in FIG. 8F. They are then combinedtogether in polarizer analyzer 146 as explained for the diagram and withreference to FIG. 8F. This combination can be of the form where thebeams are combined exactly one on the other with different polarizationsor one beam can be shifted with respect to the other so that theplurality of portions are offset from one another, or the portionsoverlap one another. Also, as explained before, the timing of the beamscan produce beams that are temporally in sync with one another or canalternate between the different fields of the desired information to bedisplayed.

[0368]FIG. 20D is the same as FIG. 20C, but with the addition of aquarter wave retarder 188 interposed between lens 148 and analyzerpolarizer 146. This variable retarder functions to alter the pluralityof portions of the segregated output beam from polarizer analyzer 146such that each altered portion has a different electric field vectororientation. Thus each altered portion may be displayed on a differentplane, such as that contained in screen or cube 175 shown in FIG. 23.

[0369] Method for Producing a High Resolution or 3-D Projected Black &White Image

[0370] Referring now to FIG. 22, an alternate embodiment high resolutionor 3-D, black and white projector is disclosed. The black and whiteprojector of FIG. 22 includes: a light source means 32 for producing acollimated source beam 50 containing white light; separation andabsorption means in the form of mirrors 33 and 35 and beam blockabsorber 161 for removing and absorbing infrared and ultraviolet raysfrom the source beam 50; polarizing means in the form of a polarizercube 36 for polarizing the source beam into two orthogonal beams, aP-polarized beam 52 and an S-polarized beam 54 with the S-polarized beamdeflected at an angle of 90°; polarization changing means in the form ofa half-wave retarder 38 for changing the direction of polarization ofthe S-polarized beam 54 to a second P-polarized beam 56; a first meansin the form of a first LCD 116 for changing the orientation of theelectric field vector of the first P-polarized beam-52 responsive to aninput image to produce an altered first beam 120; second means in theform of a second LCD 118 for changing the orientation of the electricfield vector of the second P-polarized beam 56 responsive to an inputimage to produce a second altered beam 122; a combining means in theform of a second polarizer cube 146 for combining the first 120 andsecond 122 altered beams; a second orientation of the electric fieldvector changing means in the form of a second half-wave retarder 126located in an optic path between the second LCD 118 and the secondpolarizer cube 146 for converting the direction of polarization of thesecond altered beam 122; projection lens means in the form of aprojection lens 148 for projecting a beam 128 from the second polarizercube 146 as beam 178 onto a display screen (not shown in FIG. 22); andcontrol means (not shown in FIG. 22; but see means 66 in FIG. 19) forproviding and controlling input signals to the LCDs 116, 118.

[0371] The black and white projector shown in FIG. 22 functions in thesame manner as the color projector shown in FIG. 20 without the colorseparation and combining as previously described. Moreover illuminationof the LCDs 116, 118 is similar to the method described in previoussections.

[0372] As is apparent from the previous description, first LCD 116 andsecond LCD 118 may be controlled by control means with an input image toproduce a 3-D effect or a high resolution image as previously described.That is, left eye and right eye corresponding images can be presented orencoded in different polarization states or timed sequentially or both.

[0373] Referring now to FIG. 22A, an alternate embodiment of the blackand white projector shown in FIG. 22 is shown. The alternate embodimentof FIG. 22A is exactly the same as that of FIG. 22 but with the additionof a quarter-wave retarder 188 for providing a projected image in theform of a circular polarization beam 129. As previously described, thiscan be used with circularly polarized viewer glasses for viewing a 3-Dimage.

[0374] Thus, the projector and method of the invention can also beadapted to provide a high-resolution or 3-D black and white image.

[0375] Method for Producing a 3-D Viewing screen

[0376]FIG. 23 is the diagrammatic representation of the buildup oflayers of a projection screen or the formation of a 3-D visualizationcube. Referring now to FIG. 23, a new and novel display device isdisclosed. The device acts in accordance with a beam generated by a 3-Dprojector such as disclosed in this document. The orientation of theelectric field vector can be varied by such a device as a variableretarder 188 that is placed between the beam polarizer analyzer 146 andthe output lens 148, such as shown in FIGS. 20A, 20B & 20D. This deviceacts by rotating the orientation of the electric field vector accordingto the drive electronics. This output beam is then fed into the deviceof FIG. 23. The device in FIG. 23 comprises a multiplicity of layers,each layer having a coating that is different from the successive layerwhereby each layer is reflective to a particular (or range) orientationof the electric field vector. For example, layer 200 is reflective tothe electric field vector that corresponds to a vector that has rotationbetween 0° and 5°. Layer 202 is reflective to an electric field vectorthat has an orientation between 5° and 10°. Layer 204 is reflective toan electric field vector that has a rotation between 10° and 15°. Thiswould continue on for the multiplicity of layers that are containedwithin the device in FIG. 23. Thus, when a beam is incident upon thedevice in FIG. 23, the first image plane is on layer 200, the next imageplane is on layer 202, the next image plane on layer 204, etc. The finalimage on the nth plane 216 is then reflected. By having a multiplicityof layers, images are displayed.

[0377] An alternate to the above device would replace the reflection onthe planes with ones that would absorb, with the final plane 216transmitting the remaining light.

[0378] As an alternative to the step indexes of reflection, a device isused that has a graded index of reflection with respect to the electricfield vector of rotation for each individual plane layer.

[0379] Method for Producing a Flat Fluorescent Plate

[0380]FIGS. 24 and 24A illustrates an embodiment of a flat fluorescentor neon illumination plate that is used in conjunction with FIGS. 8E,8F, 20C & 20D. A gas, 180, is surrounded by transparent plates 182 andmetallic side pieces 176 and end caps 186. A voltage difference,applicable for the proper gas, is applied between electrodes 201,causing the atoms in the gas to go into an excited state. By coating thesurfaces of the transparent plates 182 with a material that fluoresces,light will be emitted. Furthermore, a reflecting surface 184 can beapplied to further reflect all of the light out of one surface.

[0383] Method for Producing a Collimated Beam of Light

[0384]FIG. 28 is a preferred embodiment of an optical integrator/lightsource/reflector arrangement that provides a new and novel method ofproviding a collimated light beam with a substantially uniform fluxintensity substantially across the entire beam. The operation of thebasic elements are well known, however the combination of the elementsis novel. The way the device operates is as follows:

[0385] (1) light is emitted by the light source 32 in a sphericalfashion;

[0386] (2) portions of the light emitted from the light source willeither travel in the forward direction or rearward direction (as viewedin FIG. 28) and behave in the manner of one of the following four cases:

[0387] (a) strike the first lenses 45 formed on the first ends of theplurality of light pipes included in the light integrator means 63 asshown by light path 69 in FIG. 28; or

[0388] (b) strike the second concave reflecting means 65 where the lightis reflected from and directed back toward the first concave reflectingmeans 41 where it is then reflected from and directed toward the lightintegrator means 63 and strike the first lenses 45 formed on the firstends of the plurality of light pipes included in the light integratormeans 63 as shown by light path 77 in FIG. 28; or

[0389] (c) strike the first concave reflecting means 41 and be reflectedtoward the light integrator 63 where it strikes the first lenses 45formed on the first ends of the plurality of light pipes included in thelight integrator means 63 as shown by light path 67 in FIG. 28; or

[0390] (d) strike the first concave reflecting 41 where it is reflectedfrom and directed towards the second concave reflecting means 65 wherethe light is then reflected and directed back toward the first concavereflecting means 41 where it is reflected and directed toward the lightintegrator 63 to strike the first lenses 45 formed on the first ends ofthe plurality of light pipes included in the light integrator means 63as shown by light path 68 in FIG. 28;

[0391] (3) the light striking the first lenses 45 of the plurality oflight pipes will be bent according to the angle of entry and lensformula and travel through the body 75 of the light pipe and exit thelight pipe through the second lens 71 formed on the second end of thelight pipe 75; and

[0392] (4) the light at this time has substantially uniform fluxintensity and collimation, and travels to lens 43 for furthercollimation.

[0393] The light integrator means is made of a plurality of parallellight pipes such as those shown in FIG. 27A, each light pipe being[adjacent and] in contact with one or more adjacent light pipes. Eachlight pipe consists of a first lens surface 45 formed on a first endthereof, a body 75, and a second lens surface 71 formed on a second endthereof. The first lens surface 45 functions to bend light more towardsthe normal. Body 75 carries the light to the second lens surface 71 andhas the same index of refraction as the first lens surface 45 and secondlens surface 71. This minimizes the number of interfaces the light mustpass through. Continuing on, light strikes the second lens surface 71which is ground to a predetermined shape, and is again bent more normal,thus the light rays exiting surface 71 are substantially collimated.Lens surfaces 45 and 71 may or may not be of the same shape or form andare dependent upon several factors, including, but not exclusive to, thesize of the light source, the shape of the light source, the type oflight source, the distance from the light source to the first lenssurface 45, the length and size of body 75, the distance of theintegrator second lens surf ace 71 to the target, and other factorsknown in the trade.

[0394] As shown in FIG. 28, the second concave reflecting means 65 hasan opening formed therethrough in which is mounted a light integratormeans 63. The light integrator means 63 substantially occupies theopening in said second concave reflecting means 65. The light integratormeans 63 has an optical axis that is coincident with the optical axis ofthe second concave reflecting means 65. The cross section of the lightintegrator means 63 may be either rectangular, circular, elliptical,octagonal, or any desired shape. The shape of the light integrator meansis dependent upon the final desired shape of the beam formed exitingfrom the integrator.

[0395] The first concave reflecting surface means 41 has an opticalaxis. The light means 32 is mounted along said optical axis. The opticalaxes of the first and second concave reflecting means 41 and 65 arecoincident.

[0396] The system of this invention preferably includes a lens 43positioned to receive the light from the second end of the lightintegrator means 63. The lens 43 further collimates the light beam fromthe light integrator means 63.

[0397] The first and second concave reflecting means 41 and 65 arepreferably parabolic or elliptical in shape.

[0398] The optical light pipes are formed in a fly-eye arrangement injuxtaposition to each other as shown in FIGS. 27, 27B & 27C. The opticallight pipes can be of circular, rectangular, octagonal, or anyconvenient geometrical shape as required by the application intended asshown in FIGS. 27B & 27C.

[0399] The light integrator means 63 is well known in prior art, asshown in U.S. Pat. No. 4,918,583 to Kudo et al., U.S. Pat. No. 4,769,750to Matsumoto et al., U.S. Pat. No. 4,497,015 to Konno et al., U.S. Pat.No. 4,668,077 to Tanaka. These patents are mainly for forming a uniformintensity across a beam of light or ultraviolet for use in integratedcircuit manufacturing. However the interaction of the light source, thetwo reflecting surfaces and the light integrator is novel. In order tomake the system work properly, the design must take into considerationthe light source and its radiation pattern, the first and secondreflecting means 41 and 65 and the lenses 45, 71 formed respectively onthe first and second surfaces of each light pipe included in the lightintegrator means 63 and the position of the particular individual lightpipe in the matrix of the light integrator means 63. For such analysis,a commercially available computer ray tracing program such as OpticsAnalyst or Genii-Plus available from Genesse Optics Software, Inc., 3136Winton Road South, Rochester, N.Y., 14623 or Beam Two, Beam Three, orBeam Four from Stellar Software, P.O. Box 10183, Berkeley, Ca., 94709can be used in the design of the lens and reflecting means formula forthe shapes needed in regard with the particular light source that ischosen.

[0400] Thus, the invention provides a color liquid crystal light valveLCD projector that produces an image of high brightness, contrast andresolution. Additionally, harmful infrared and ultraviolet rays havebeen removed from the projected image. Moreover, in light of the hereindescribed invention, components of the system can be modified or easilyadjusted to produce a color enhanced image.

[0401] At the present time, the overall preferred single embodiment of aprojector constructed in accordance with the invention disclosed hereinis a projector for producing a modulated beam of light suitable forprojection of video images, comprising: means for providing a firstinitial beam of light having randomly changing orientations of theselected component of the electric field vectors; means for integratingthe first initial beam of light to form a second initial beam of lighthaving a substantially uniform flux intensity across substantially theentire second initial beam of light; means for collimating the secondinitial beam of light into an initial collimated beam of light havingrandomly changing orientations of the selected component of the electricfield vectors and a substantially uniform flux intensity acrosssubstantially the entire second initial beam of light; means forremoving from the initial collimated beam of light at least a portion ofultraviolet and infrared to produce an initial collimated beam of whitelight and directing the removed portions to a beam stop whereby theremoved portion is absorbed; means for resolving from the initialcollimated beam of white light an initial collimated first resolved beamof white light having substantially a first single selectedpredetermined orientation of a chosen component of the electric fieldvectors and an initial collimated second resolved beam of white lighthaving substantially a second single selected predetermined orientationof a chosen component of the electric field vectors, whereby the firstand second single selected predetermined orientation of the chosencomponent of the electric field vectors are different from one another;means for forming from the initial collimated first resolved beam ofwhite light and initial collimated second resolved beam of white light asubstantially collimated rectangular initial single beam of white lighthaving substantially the same single selected predetermined orientationof a chosen component of the electric field vectors across substantiallythe entire beam of light and a substantially uniform flux intensityacross substantially the entire initial collimated single beam of whitelight; means for separating the collimated rectangular initial singlebeam of white light into two or more separate collimated rectangularbeams of color whereby each of the separate collimated rectangular beamof color has the same single selected predetermined orientation of achosen component of the electric field vectors as that of the otherseparate collimated rectangular beams of colors and each separatecollimated rectangular beam of color having a different color from theother separate collimated rectangular beams of colors; means foradjusting the color by removing at least a predetermined portion ofcolor of at least one of the separate collimated rectangular beam ofcolors and directing the removed portion to a beam stop whereby theremoved portion is absorbed; means for altering the single selectedpredetermined orientation of the chosen component of the electric fieldvectors of a plurality of portions of each separate collimatedrectangular beam of color by passing a plurality of portions of eachseparate collimated rectangular beam of color through a respective oneof a plurality of altering means whereby the single selectedpredetermined orientation of the chosen component of the electric fieldvectors of the plurality of portions of each separate beam of color isaltered in response to a stimulus means by applying a signal means tothe stimulus means in a predetermined manner as the plurality ofportions of each of the substantially collimated separate beams ofelectromagnetic energy passes through the respective one of theplurality of altering the single selected predetermined orientation of achosen component of the electric field vectors; means for combining thealtered separate collimated rectangular beams of color into a singlecollimated rectangular collinear color beam without substantiallychanging the altered selected predetermined orientation of the chosencomponent of the electric field vectors of the plurality of portions ofeach separate collimated rectangular beam of color, means for resolvingfrom the single collimated rectangular collinear color beam a firstcollimated rectangular resolved color beam having substantially a firstsingle selected predetermined orientation of a chosen component of theelectric field vectors and second collimated rectangular resolved colorbeam having substantially a second single selected predeterminedorientation of a chosen component of the electric field vectors, wherebythe first and second single selected predetermined orientation of thechosen component of the electric field vectors are different from oneanother; and means for passing one of the first collimated rectangularor second collimated rectangular resolved color beam to a projectionmeans.
